At least 30 people were feared trapped after a methane explosion collapsed a coal mine Tuesday on the island of Sumatra in Indonesia. "We received reports of the collapsed mine around midday Tuesday, local time. Thirty people are feared still in the mine when it collapsed, while the other nine have been pulled out," said Yanuar of the Padang search and rescue team, who uses one name, as many people do in Indonesia. Rescuers from the nearby cities of Sawahlunto and Solok had been dispatched and were racing to save the miners, he was quoted as saying by CNN. The Sawahlunto area is known for its rich coal and has been mined since 1875.
